If you receive a sensor failure SF2 a possible cause may be
the process temperature sensor failed. Check with OHM
meter and see if the resistance matches the table below.
Replace if needed. In addition the sensor wiring may be
incorrect or failed. If this is the case check all wiring from
terminal strip to sensor in question. Repair as necessary.
